A laser beam source (LIK) is a welding technique used to join together metal or thermoplastic particles using a laser. A concentrated heat source provides solid, narrow, deep sources and high source rates. As in the automotive industry, the process is often used in high-volume applications that use automation. Keyhole or penetration mode depends on the source. Image/Audio Courtesy: Unknown DM for credit or removal request. Use intended only for knowledge and information purposes. #civilengineeri
